Relating characteristics of global biodiversity targets to reported progress

To inform governmental discussions on the nature of a revised Strategic Plan for Biodiversity of the Convention on Biological Diversity (CBD), we reviewed the relevant literature and assessed the framing of the 20 Aichi Biodiversity Targets in the current strategic plan. We asked international experts from nongovernmental organizations, academia, government agencies, international organizations, research institutes, and the CBD to score the Aichi Targets and their constituent elements against a set of specific, measurable, ambitious, realistic, unambiguous, scalable, and comprehensive criteria (SMART based, excluding time bound because all targets are bound to 2015 or 2020). We then investigated the relationship between these expert scores and reported progress toward the target elements by using the findings from 2 global progress assessments (Global Biodiversity Outlook and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services). We analyzed the data with ordinal logistic regressions. We found significant positive relationships (p < 0.05) between progress and the extent to which the target elements were perceived to be measurable, realistic, unambiguous, and scalable. There was some evidence of a relationship between progress and specificity of the target elements, but no relationship between progress and ambition. We are the first to show associations between progress and the extent to which the Aichi Targets meet certain SMART criteria. As negotiations around the post-2020 biodiversity framework proceed, decision makers should strive to ensure that new or revised targets are effectively structured and clearly worded to allow the translation of targets into actionable policies that can be successfully implemented nationally, regionally, and globally.     

基站电磁辐射防护与环境监管对策分析

移动通信基站是实现通信信号覆盖的重要设备,是保证移动信号覆盖范围与信号质量的基础支撑。现阶段,随着我国现代化、城市化进程不断加快,移动通信基站的架设密集度极大的增加,为实现移动信号全覆盖,为人们的生产生活提供便利发挥重要作用。但是,基站运行过程中,产生的电磁辐射可能会对人体健康造成不利影响。因此,加强基站电磁辐射防护与环境监管是非常必要的。本文对基站电磁辐射安全距离的有效评估进行了分析,提出了基站电磁辐射防护与环境监管的有效对策。

“十四五”时期危险废物污染防治思路探讨

"十三五"时期,我国环境质量改善和生态文明建设取得显著进展,"十四五"时期生态环境保护面临的形势和任务仍然严峻艰巨,亟须正确识别当前的环境形势以及未来的重大环境问题,制定针对性的规划。本文概述了"十三五"期间我国危险废物污染防治取得的进展和成效,并分析了当前危险废物环境风险防控面临的废物产生量大且持续增加、环境风险高、利用处置短板凸显、综合利用风险防控不足等突出问题,从制度优化、科学管理和技术支撑等重点任务、重大工程方面,提出"十四五"环境保护危险废物污染防治规划思路,为编制"十四五"危险废物污染防治规划提供参考。     

我国“十四五”时期农村环境保护总体思路探讨

打好升级版污染防治攻坚战,思路创新与转型是关键。我国农村环境保护底子薄、基础差、欠账多,现阶段农村环境治理仍是经济社会发展的突出"短板"和显著"弱项"。本文在分析"十四五"时期农村环境保护工作基础和面临形势的基础上,提出以改善农村环境质量、提高农村环境治理体系和治理能力现代化水平为核心,以解决农民群众身边最紧迫、最直接的突出生态环境问题为导向,聚焦农村生态、农业生产、农民生活三大重点领域,统筹城乡污染治理体制机制,推动建立多元共治体系,打通"两山"转化通道,打好升级版的农村污染防治攻坚战的总体思路,助力乡村振兴战略,全面提升农村生态文明和绿色发展水平。     

“十四五”生态环境保护国际合作思路与实施路径探讨

生态环境国际合作是构建人类命运共同体建设的重要内容。"十三五"时期,我国在推动生态文明建设取得显著成效的同时,生态环境保护国际合作取得积极进展。本文在分析生态环境保护国际合作现状、不足以及面临新形势的基础上,提出坚持底线思维,突出重点,精准对接,以我为主、以外促内等合作原则,建议"十四五"时期加强战略规划和引领,提升生态环境国际合作的地位和作用,以建设性姿态参与全球环境治理,努力实现国内环境治理、全球环境治理以及全球治理良性互动,提升生态环境国际合作在服务国家总体发展战略中的地位和水平。并为此提出五大重点举措:即打造绿色"一带一路"成为区域环境合作的平台高地;更具建设性加强我与周边国家双边及多边环境合作;坚决维护多边主义的立场,主动参与全球环境治理体系变革;助力擦亮绿色底色,全力支撑服务打赢污染防治攻坚战;加快能力建设形成生态环境国际合作与交流的大格局。     

“十四五”推动绿色消费和生活方式的政策研究

当前,中国消费规模持续快速扩张,居民消费已从温饱向小康转型升级,消费对中国经济增长的贡献率快速提升,成为驱动经济增长的重要引擎。前期研究表明,消费领域的绿色转型有助于引导和倒逼生产的绿色化,促进形成绿色生产生活方式,带动公众积极践行绿色理念,改善社会绿色转型的治理体系,将对中国整体绿色转型和高质量发展发挥决定性作用。在此基础上,本文研究提出了中国“十四五”时期推动绿色消费的总体目标、指标体系和重点领域,认为中国政府应将绿色消费放在更加突出的战略位置,通过“十四五”规划全面推动相关实践,按照供给侧与需求侧共同发力、激励约束并举、政府企业消费者共建共治共享的原则,构建绿色消费政策体系,并针对建筑、汽车、电力、物流等重点行业提出了具体的政策建议。

The Costs of Meeting the Environmental Objectives for the Baltic Sea: A Review of the Literature

The environmental targets of the recently agreed Baltic Sea Action Plan (BSAP) targets are likely associated with a considerable cost, which motivates a search for low-cost policies. The following review shows there is a substantial literature on cost-efficient nutrient reduction strategies, including suggestions regarding low-cost abatement, but actual policies at international and national scale tend to be considerably more expensive due to lack of instruments that ensure a cost-efficient allocation of abatement across countries and sectors. Economic research on the costs of reducing hazardous substances and oil spill damages in the Baltic Sea is not available, but lessons from the international literature suggest that resources could be used more efficiently if appropriate analysis is undertaken. Common to these pollution problems is the need to ensure that all countries in the region are provided with positive incentives to implement international agreements.     

Ensemble Modeling of the Baltic Sea Ecosystem to Provide Scenarios for Management

We present a multi-model ensemble study for the Baltic Sea, and investigate the combined impact of changing climate, external nutrient supply, and fisheries on the marine ecosystem. The applied regional climate system model contains state-of-the-art component models for the atmosphere, sea ice, ocean, land surface, terrestrial and marine biogeochemistry, and marine food-web. Time-dependent scenario simulations for the period 1960–2100 are performed and uncertainties of future projections are estimated. In addition, reconstructions since 1850 are carried out to evaluate the models sensitivity to external stressors on long time scales. Information from scenario simulations are used to support decision-makers and stakeholders and to raise awareness of climate change, environmental problems, and possible abatement strategies among the general public using geovisualization. It is concluded that the study results are relevant for the Baltic Sea Action Plan of the Helsinki Commission.
